Aiming at fixing the shortcomings of using fuzzy Cmeans algorithm solely to solve fuzzy clustering problems, first, this paper proposed an improved gravitational search algorithm by updating the velocity of individuals according to a probability, expanding the search space effectively. Secondly, a fuzzy gravitational search algorithm (FGSA) was proposed. Finally, a novel hybrid algorithm (FGSAFCM) based on a fuzzy improved gravitational search algorithm (FGSA) and fuzzy cmeans algorithm (FCM) was proposed to solve fuzzy clustering problems. Fuzzy cmeans algorithm is very sensitive to initialization and easily gets into local optima, but the new algorithm may avoid these shortcomings. This paper chooses the objective function and validity function as the evaluation criterion. The FGSAFCM was tested on ten classic datasets, and the experiment results show that the new algorithm is more accurate and robust than the sole fuzzy cmeans algorithm.
